and useful Improvements in Brick-Machines,

of which the following is a specification.

. The invention has to do with improved means, simple and efiiclent, for lmparting to, bricks in the act ofmoldmg a characteristlc surface marking such as a rough or stippled face. H a

In order that the invention may be readscription based thereon. Obviously, however, the inventlon is susceptlble of embod ment in other and varied constructional forms without departure from the tessence thereof, wherefore the drawlng and descript1on are to be taken 111 an 1llustrat1ve rather than in an unnecessarily limiting sense. In

the drawings a t 1 Figure l is an end elevation, fragmentary in character, showing the salient parts of the brick machine embodying the invention, the medial portion being broken away on a line 11 of-Fig. 2, below the horizontal level illustrated in said figure; F1g.'2 is a plan vlewwithfithe portion shown in horlzontal section;

Fig. 3 is a fragmentary view in end eleva-a tlonof a portion shown in Flg. 1, lllllStlitt-f ing the parts in a different position; Fig. 4 is a side elevation withcertain parts shown in vertlcal section onthe line 4 4of Flg. 1 and a upper battery of rams 15, 16, 17 i and 18, ar-

ranged side by side andsuppliedwithmaterial from the hopper indicated at 19, the

two members of each pair of rams disposed end to end and acting upon material fed therebetween, the formed brick beingedischarged from the mold onto the table 20.

Themachine provides means for impart central I H h p gles to the shaft 22. The shafts 35,, 36 have ingdesiredrough configuration, herein gen-;

end and edge faces f the bricks are stippled 1n the act of molding the same, the stipple plates being .so mounted as to be suddenly removed from contact with the formed brick by a swingingor rectilinear movement as the brick reaches a position ready tobedis charged-onto the table 20.

Carried by the mounting-of the upper sets of rams 15, 16, 17 and 18 in suitable bearings, forupward and downward movement with the rams, are two parallel shafts 2land 22 which are geared by means of the meshing pinions23,24, the shaft 21 having-fixed.thereonltwo crank arms'25 and 26, the fornier connected by means of an expanslon spring 27 with a suitable support 28 for rocking the shaft 21 in one direction and the latter. arm 26 being. provided with a roller 29 adapted to be engagedby the lower end of avertically adjustable trip bar 30 asthe upper battery erm ne rise, whereby to'rock' the shaft 21in the opposite direction, The shaft 22 has fixed thereon bevel gears 31, "32, inmesh with bevel gears 33, 34 carriedby shafts 35-, 36arranged at right an= suspended therefrom respectively stipple plates 37 ,38, and the shaft 22 has suspended therefrom four similar stipple plates 39, 40 41 and 42.

The said stipple plates 37 and. 38 are adapted to surface the edges of the brick formed inthe outside molds of the battery while the plates 39, 40, 41 and 42 are arranged to surface the end faces of all four bricks turned out by the battery of molds.

The stipple plate for surfacing the edges of the intermediate bricks of the battery of molds are-differently mounted and operated as will now be described.

Between eachof the intermediate rams and its adjacent outside ram there is provideda space 43 on the one hand and 44 on the other, and also a central space 45. Transversely slidably mounted in the rams 16 and 17 are arranged rods 46- and 47, 4S

. and 49. The rods 46 and 47 of the ram 16 and 52, 53 on the other is a wedge member 56 having an overhanging lip 57 extending beyond the shaft 22 and inclosing an eccentric 58 fixed upon said shaft 22, the rocking of the shaft 22causing the wedge member 56to be reciprocated, thus wedging apart the wedge blocks 5052 and 51-53, 00111- pressing the springs 59, 60, 61 and 62 which encircle the rods 46, 47, 48 and 49 and moving the stipple plates 54 and 55 outwardly from the position shown in Fig. 2 to that shown in the central part of Fig. 3. J

In operation *the material supplied by the hopper 19drops into the cavity 63 of the plunger feed 64, restingupontliefeed table at 65. The plunger 64 moves forwardly beneath the elevated battery of rams 15, 16, 17 and 18 while the stipple plates 37, 38, 39, 40, 41 and 42 are swung outwardly to the position indicated in Fig. 3 in full lines as to one of said stipple plates, and as indicated in dotted lines in Fig. 4

. as to other of said stipple plates, the stipple plates 54 and 55 also being in retracted position as indicated in Fig. 3. The material, carried forward in the cavity 63 by the advancing plunger 64, drops'into the mold .cavity resting upon the upper face of the lower battery of rams 11, 12, 13, and 14 and any excess of material is'removed to the table 65 by the advance portion 64 of the plunger as said plunger recedes to the posi-' tion shown in Figs. 4 and 5. As the upper battery of rams starts to descend, sprin 27 rocks the shaft 21 and through it the shaft 22 causing the stipple plates 37 38, 39, 40, 41 and42 to swing to a vertical position and the stipple plates 54 and 55 to move in wardly under the action of the springs 59,

60', 61 and 62. In this position the stipple plates are immediately above the end and one side face of each of the mold cavities and, as the rams descend these stipple plates enter the molds and form liners therefor, the displaced material escaping through the vent slots 66. As is customary, the lower battery of rams 11, 12, 13 and 14 ascend as the upper battery 15, 16, 17 and '18 descend compressing the material therebetween and against the sidefaces and liner plates of the mold. Due compression having been exerted upon the material in the' molds both sets of rams move upwardly until the bricks within the mold reach the level of the discharge table 20, this position being indicated in Fig. 4. Further'a scent of the rams 15, 16, 17 and 18 causes the roller 29 g to engage the trip 30 quickly swinging the stipple plates 37, 38, 39, 40*, 41 and 42 to an elevated position away from the brick face and at the same time moving the stipple plates 54and 55 away from the brick face.

Thereupon the plunger 64 moves forward with a new load of material, the projection 64 pushing the formed brick off the lower ram onto the'discharge table 20 as shown in Fig. 4 and filling the mold for theneXt set of bricks; the operation being then repeated.
